Josephus问题

我的解法：

#include <iostream>
#include <list>

using namespace std;

int main()
{
    int i,j,n,m,mPrime,numLeft;
    list<int> L;
    list<int>::iterator iter;
    //初始化
    cout<<"enter N(# of people)&M(# of passes before elimination)";
    cin>>n>>m;
    numLeft=n;

    mPrime=m%n;
    for(i=1;i<=n;i++)
    {
        L.push_back(i);
        
    }
    iter=L.begin();
    for(i=0;i<n;i++)
    {
        mPrime=m%numLeft;
        
            for(j=0;j<mPrime;j++)
            {
                iter++;
                if(iter==L.end())
                    iter=L.begin();
            }
        
        
        cout<<*iter<<" ";
        iter=L.erase(iter);
        numLeft-=1;
        if(iter==L.end())
            iter=L.begin();
    }
    cout<<endl;
    return 0;
}
